My 21 week of pragnancy is running...I'm only sit one hour properly after that it is it because of my sac separation problem which is starts in my 14 week. wat I hv to do..

Sac separation if detected early generally repairs by this time of pregnancy. Pregnant moms are not supposed to sit or stand in one place for long hours. It is not good for your circulation. This is your body's natural reaction which is telling you please get up and move around and stretch a little.
